Unless you happen to be in the unlikely situation of being the only company in the world that does what you do then the chances are you have competitors!
So how do you differentiate yourself?
Generally we compete either on price or quality. There are benefits to both.
For the industry we are in and for most of our clients there will always be someone cheaper who has better economies of scale or just is happy to produce inferior goods or services.
So the more logical conclusion and that of a company which takes pride in its work is to be better than the competition.
You don’t need to be the cheapest but if your work is excellent then clients come to you and recommend you on because they value quality and want to continue the same values to their client base.
Having taken the decision that this will be your business strategy then everything you produce, do or say should be about establishing yourself as expert in your industry and a bastion of quality that will be reflected in the work you do.
Your website (there was a point to all of this) is an excellent opportunity for you to establish yourself as an expert to your client (and perhaps even more importantly potential client) base.
Think about (or talk to your web designers about) how you can best use your website and general online marketing strategy to show the world how much you know about your industry, how much you understand about your clients and their requirements and how much you care about getting it just right.
